Maximum-likelihood Poisson regression

Command line:

^poisml^ depvar [varlist] [weight] [^if^ exp] [^in^ range] [, ^lt(^#^) ir^r ^off(^var^) nol^og^ rob^ust ^score^(var)^ cl^uster(var)]

^lt(#)^ = tolerance for convergence ^irr^ = parameter estimates displayed in exponential form; standard errors and CIs adjusted ^off(str)^ = offset variable - log raw var prior to using as offset ^nolog^ = no display of iteration log ^robust^ = displays robust variance estimator; auto w cluster ^cluster(str)^ = identifies variable used for clustering ^score(str)^ = creates a variable with score value

Results may be redisplayed by entering the command. Exponential form and C.I. level are allowed as options without reestimation.
